| Fez-se o levantamento florístico da vegetação arbórea da floresta mesófila do Parque Estadual do Morro do Diabo, Município de Teodoro Sampaio, Estado de São Paulo (22º30'S, 52º20'W) pelos métodos de quadrantes e parcelas, incluindo as árvores com diâmetro à altura do peito igual ou superior a 10 cm. A utilização dos dois métodos deu-se em função das características fisionômicas, solo e drenagem dos locais amostrados. O método de quadrante envolveu 462 pontos com intervalos de 30 m., e o método de parcelas ca. 26.900 m² (ca. 2,7 ha.). Os parâmetros fitossociológicos serão abordados em futuros trabalhos. Os dados florísticos subsidiaram o reassentamento dos grupos faunísticos, em especial o Leontopithecus chrysopygus Mikan, 1823 (mico-leão-preto), dentro das... |

| Abstract Ecological capability evaluation is referred to as evaluation of potential capability of land and determination of its natural land use. In this paper, ecological capability of Lille Basin in Lahijan was evaluated for afforestation and forest expansion using Geographical Information Systems (GIS). For this purpose, information layers (slope, elevation, geographical directions, temperature, rainfall, humidity, soil type, and canopy cover) were prepared by digitizing the data obtained from concerned organizations. First, the layers were prepared based on coordinate systems and pixel value. Then, they were standardized using fuzzy membership functions. The evaluation criteria were prioritized with regard to expert opinion, and by using multi-criteria... |

| The process of land occupation by the state of Paraná practically decimated its forests. Presently, only 7% from a total area of 83.41% is covered by forests. Most of them are now concentrated in the "Serra do Mar" and in the Iguaçu National Park. With regard to forest cover the most critical region is situated in the northwestern of the state with less than 1% of its area covered by forest. This restricted area mainly consists of conservation units and the islands of the high Paraná River floodplain. The present study consists of a spatial and multi-temporal analysis of deforestation and the quantification of the remnant forests on Porto Rico island (22º45'S; 53º15'W), which have their occupation history linked to the colonization process of the region.... |

| The objective of this study was to assess the physical attributes of a kaolinitic oxisol, medium texture (Haplustox) and an oxidic oxisol, clayey (Eutrustox) under different usage systems, localized in the region of Jaboticabal, SP, Brazil. The usage systems were sugarcane, cotton and forest. Parameters such as soil bulk density, total porosity, macro and microporosity at the depths of 0.0-0.1; 0.1-0.2; 0.2-0.3, and 0.3-0.4 m were evaluated. Haplustox showed greater bulk density and smaller total porosity, macro and microporosity. The usage increased the bulk density in 0.0-0.3 m depth, with greater effects on the kaolinitic oxisol, mainly in 0.1-0.2 m depth in the areas cultivated with sugarcane. |

| ABSTRACT: The objective was to estimate the wood yield and essential oil content in three clones of eucalyptus that were planted in four contrasting arrangements and intercropped with sorghum. Eucalyptus clones MA2001 (Eucalyptus camaldulensis x E. tereticornis), A144 (Eucalyptus urophylla x E. grandis), and GG100 (Eucalyptus urophylla x E. grandis), were planted in single rows (10x2m), double rows (2x3+15m and 2x3+20m); and, triple rows (2x3x2+10m) in a randomized, complete block design experiment with four replicates. Our results demonstrated that planting spacing did not influence the essential oil yield or diameter at breast height in the clones. However, higher density plantings were shown to result in higher fresh weight of branches and leaves per... |
